The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; show every role.

The impact of event colour structure on the performance of the Johns-Hopkins, CMS, HEPToptagger and N-Subjettiness algorithms is investigated by studying colour singlet and colour octet resonances decaying to top-quark pairs. Large differences in top-tagging efficiency are observed due to the different colour charge of each resonance. These differences are quantified as a function of the algorithm parameters, the jet size parameter and the probability to misidentify light quarks and gluons as top candidates. We suggest that future experimental searches would benefit from optimising the choice of algorithm parameters in order to minimise this source of model dependency.

Original abstract

The impact of event colour structure on the performance of the Johns-Hopkins, CMS, HEPToptagger and N-Subjettiness algorithms is investigated by studying colour singlet and colour octet resonances decaying to top-quark pairs. Large differences in top-tagging efficiency are observed due to the different colour charge of each resonance. These differences are quantified as a function of the algorithm parameters, the jet size parameter and the probability to misidentify light quarks and gluons as top candidates. We suggest that future experimental searches would benefit from optimising the choice of algorithm parameters in order to minimise this source of model dependency.

Search for resonances decaying into top-quark pairs using fully hadronic decays in pp collisions with ATLAS at sqrt(s) = 7 TeV
hep-ex 2012-11 conditional novelty 5.0 of 10

No resonant top-pair excess appears in 4.7 fb^-1 of 7 TeV ATLAS data, excluding Kaluza-Klein gluons from 0.70 to 1.62 TeV and Z' bosons in two windows at 95% credibility.
Adversarially-trained autoencoders for robust unsupervised new physics searches
hep-ph 2019-05 conditional novelty 4.0 of 10

Adversarial training removes an autoencoder anomaly detector's dependence on jet and missing-energy smearing in simulated boosted top-pair resonance searches, at a small cost in raw discrimination.
Looking inside jets: an introduction to jet substructure and boosted-object phenomenology
hep-ph 2019-01 conditional novelty 3.0 of 10

The manuscript is a comprehensive pedagogical review of jet substructure and boosted-object phenomenology, synthesizing standard QCD calculations, algorithms, and LHC applications without presenting new research results.

6 arXiv papers cite this in 6 sentences

Each citing sentence is taken from the citing paper's LaTeX source and typed by Pith's classifier. A label appears at probability 0.8 or more (0.95 for support), a contest at 0.7 or more; the quoted words are the citing authors'. How each label was checked · JSON

Uses the method or tool of 1 paper

The Cambridge-Aachen (CA) algorithm [ref] as implemented in Fastjet [ref] is used to reconstruct jets using all stable final state interacting particles[i.e. excluding neutrinos] with $|η|<4.9$, which is the coverage of the ATLAS and CMS calorimeters.

We compared the results of using the two parton shower options to the ATLAS data [ref] in Fig. [ref] and concluded that the wimpy showers give a better description of the data.
